VINE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 493,322, dated March14, 1893.

Application filed October 28, 1892. Serial No. 450,294. (No model To allwhom t may concern.-

Be it known that I, JOHN H. WHEELER, a citizen of the United States,residing at Macy, in the county of Brazos and State of Texas, haveinvented a new and useful Vine-Cutter, of which the following is aspecification.

This invention relates to vine cutters, and has for its object tosimplify the construction of devices of this character by means of anintegral formation of the cutter, and with this object in view theinvention consists of the construction and arrangement of the parts aswill be hereinafter more fully described and claimed.

In the drawings: Figure l is a perspective View of a plow-frame showingthe improved device applied in connection therewith. Fig. 2 is a bottomplan view of the device as shown in Fig. l. Fig. 3 is a detailperspective view of the improved device detached.

Similarnum erals of reference designate corresponding parts in theseveral views.

Referring to the drawings, the numeral l designates the plow-beam,having handles 2, and a depending post or standard 3. To the lowerportion of the post or standard 3 is secured the improved cutter 4t,which consists of a pair of cutting knives or shares 5, which areslightly divergent and are integrally connected by a front cross-piece6, with a central opening 7 therein for the passage therethrough of thesecuring bolt. The lower edges of the cutting knives or shares aresharpened, as at 8, and the rear ends are curved upward, as at 9,through which the sharpened portion is continued,and said cutting knivesor shares are given a slight concavo convex formation in the directionof their Width in order to provide for a more perfect-draw-cut. Adjacentto the opposite terminations of the cross-piece 6, the cutting knives orshares are formed with blunt lower edges l0 and are decreased in width,because at this point the formation of the cutting edge is unnecessaryin view of the fact that it lies against the opposite sides of the postor standard.

In applying the improved cutting device to the post or standard ot' theplow-frame, the cross-piece 6 is placed over the front edge or side ofthe lower portion of said standard and a single securing-bolt 11 passedtherethrough, this being the only means of securement necessary in viewof the opposite inner opposing sides of the cuttingknives or sharesbearing against the opposite edges of the said post or standard. Thisarrange ment prevents loose movement of the cutting attachmentin anydirection and provides for ready engagement and disengagement of thesaid device with or from the post or standard.

A further important advantage gained by the construction set forthresides in the resiliency supplied to the cutting knives or sharesthrough the medium of their integral connection with the cross-piece 6,and permitting them to have slight lateral movement to freely pass overobstructions, if the latter exist, without danger of breaking orstraining the said cutting knives or shares.

It will be seen that the cutting knives or shares are so arranged as tosimultaneously cut the vines on both sides of a row and saveconsiderable labor and time by the double operation.

The device may be constructed of suitable metal of a proper grade oftemper or degree of hardness, and after it has been usedin the mannerstated a following plow can be employed to advantage in the furrowsbetween the rows for covering the vines.

The construction set forth is comparatively inexpensive in manufacture,easily and readily applied, and forms a useful and convenientacquisition to agricultural implements.

Having described the invention, what I claim as new isl As an improvedarticle of manufacture, a vine-cutting attachment adapted to be appliedto a plow standard or foot consisting of a pair of cutting knives orshares integrally connected by a front cross-piece with a single centralopening therein for the passage therethrough of a single securing bolt,the knives being rearwardly divergent and obliquely arranged at adownward angle, the lower edges of said knives or shares being sharpenedand their rear ends curved upwardly, the said lower edges of the knivesor shares adjacent to the said cross-piece being formed blunt,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
